Alex Lyu is an artist who explores the impact of authority on individuals through installation. In "Flow and Cover," Lyu uses meetings as a carrier, exploring the crafting of hierarchical relationships between superiors and subordinates by formalism and authoritarianism. Through creating this artwork, Lyu aims to peel back the layers of superficiality and inefficiency that are deeply embedded in the formalistic and authoritarian structures prevalent in modern Chinese meetings, providing a metaphorical critique of the perfect appearance of formalism carefully maintained through seating arrangements in such meetings and the deep-rooted hierarchy of identities beneath the surface.
